HOUSTON— Exactly 15 years ago, flares of light streamed across the North Texas sky, signaling the end of a space shuttle’s era and the lives of its crew.
On Feb. 1, 2003, the Space Shuttle Columbia broke into pieces as it re-entered Earth's atmosphere.
The shuttle was 210,000 feet up and about 16 minutes from its final destination when the spacecraft began coming apart. A chunk of foam from the shuttle's external tank came off during lift-off, leaving a puncture in the left wing and dropping the chances for a safe re-entry.
Today, there was a moment of silence for those heroes during an Educator’s Conference at Space Center Houston.
It's hard to believe it's been 15 years since the horrific tragedy, but a solemn reminder, we are all, indeed, human.
